On the left hand side of each post you will find the poster's name. If you left click on the name it will allow you to add them to your contact list. That will also allow you to make a request to them to become your friend. Don't bother clicking mine. I refuse all such requests because I don't want to leave the impression that I am friends with some and not with all. Also remember, the best way to make a friend is to be a friend.
